CCNA Security Chapter 8 Lab A Objectives Part 1: Configure Basic Device Settings Configure hostnames, interface IP addresses, and access passwords. Configure the OSPF dynamic routing protocol. Part 2: Configure a Site-to-Site VPN Using Cisco IOS Configure IPsec VPN settings on R1 and R3. Verify site-to-site IPsec VPN configuration. Test IPsec VPN operation. Background / Scenario VPNs can provide a secure method of transmitting data over a public network, such as the Internet. VPN connections can help reduce the costs associated with leased lines. Site-to-Site VPNs typically provide a secure (IPsec or other) tunnel between a branch office and a central office. Another common implementation of VPN technology is remote access to a corporate office from a telecommuter location, such as a small office or home office. In this lab, you will build and configure a multi-router network, use Cisco IOS to configure a site-to-site IPsec VPN, and then test the VPN. The IPsec VPN tunnel is from R1 to R3 via R2. R2 acts as a pass-through and has no knowledge of the VPN. IPsec provides secure transmission of sensitive information over unprotected networks, such as the Internet. IPsec acts at the network layer and protecting and authenticating IP packets between participating IPsec devices (peers), such as Cisco routers. Note : The router commands and output in this lab are from a Cisco 1941 router with Cisco IOS Release 15.4(3)M2 (with a Security Technology Package license). Other routers and Cisco IOS versions can be used. See the Router Interface Summary Table at the end of the lab to determine which interface identifiers to use based on the equipment in the lab. Depending on the router model and Cisco IOS version, the commands available and output produced might vary from what is shown in this lab. Note : Before beginning, ensure that the routers and the switches have been erased and have no startup configurations. Required Resources 3 routers (Cisco 1941 with Cisco IOS Release 15.4(3)M2 image with a Security Technology package license) 2 switches (Cisco 2960 or comparable) (not required) 2 PCs (Windows 7 or Windows 8.1, SSH Client, and WinRadius) Serial and Ethernet cables, as shown in the topology Console cables to configure Cisco networking devices © 2019 Cisco and/or its affiliates.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
